Optimization of process parameters for minimizing porosity level and maximizing hardness of AA2024 alloy coating on AZ31B alloy using computational response surface methodology
The main aim of this study is the optimization of process parameters for minimizing the porosity level and maximizing the hardness of AA2024 alloy coating developed on AZ31B alloy using twin wire arc spray technology. To achieve this objective, the stastical and computational approach of response surface methodology was employed. The empirical relationships were established for predicting the porosity and hardness of coating. The empirical relationships were validated using analysis of variance (ANOVA). The design expert software 13.0 was used for performing the response surface methodology and ANOVA. Results showed that the lowest porosity level of 1.21% and maximum hardness of 135 HV was obtained when coated using laser power of 5 kW, air pressure of 3.5 bar, and stand-off distance of 200 mm stand-off distance. The empirical relationships accurately predicted the porosity level and hardness of coating within 5% of error and 95% confidence.
